The U.S. Military Is Running a Bitcoin Node, Admiral Paparo Reveals
The United States military has an active node on the Bitcoin network, according to Admiral Samuel Paparo, commander of U.S. Indo-Pacific Command (INDOPACOM). The disclosure, made at a House Services committee hearing, marks the first known confirmation that a U.S. military combatant command is directly participating in the Bitcoin peer-to-peer network.
“We have a node on the Bitcoin network,” Paparo wrote. “We’re doing a number of operational tests to secure and protect networks using the Bitcoin protocol.”
The statement landed one day after Paparo made waves in Congress with testimony that framed Bitcoin as a tool of American power.

What Paparo said yesterday
On April 21, Paparo testified before the Senate Armed Services Committee during a FY2027 defense authorization hearing. Sen. Tommy Tuberville (R-AL) asked Paparo whether U.S. leadership in Bitcoin could give the country an edge against China in the Indo-Pacific theater.
Paparo did not deflect. He told the committee that INDOPACOM’s research centers on Bitcoin as a computer science tool — not as a financial asset.
“Our research into Bitcoin is as a computer science tool,” Paparo said. “It’s the combination of cryptography, a blockchain, and a proof of work. And Bitcoin shows incredible potential as a computer science tool that through the proof-of-work protocols, actually imposes more cost than just the algorithmic securing of networks and our ability to operate.”
He described Bitcoin as “a peer-to-peer, zero-trust transfer of value” and said that “anything that supports all instruments of national power for the United States of America is to the good.”
The testimony was notable for what Paparo did not say. He did not describe Bitcoin as a reserve asset, a payment system, or a speculative instrument. He framed it as a computer science system with direct military relevance — a distinction that set his remarks apart from most official government commentary on crypto.
What running a Bitcoin node means
A Bitcoin node is a computer that runs the Bitcoin software, maintains a full copy of the blockchain, and independently validates every transaction and block against the network’s consensus rules. Nodes do not mine Bitcoin. They enforce the rules of the protocol and relay data across the peer-to-peer network.
Running a node gives an operator direct, trustless access to the Bitcoin network without relying on any third party. The operator’s computer connects to other nodes worldwide, verifies incoming transacti
